Class Declaration
Following is the declaration for java.util.zip.DeflaterInputStream class −
public class DeflaterInputStream extends FilterInputStream
Fields
Following are the fields for java.util.zip.DeflaterInputStream class −
-
protected byte[] buf − Input buffer for reading compressed data.
-
protected Deflater def − Compressor for this stream.
Constructors
| Sr.No. | Constructor & Description |
|---|---|
| 1 |
DeflaterInputStream(InputStream in) Creates a new input stream with a default compressor and buffer size. |
| 2 |
DeflaterInputStream(InputStream in, Deflater defl) Creates a new input stream with the specified compressor and a default buffer size. |
| 3 |
DeflaterInputStream(InputStream in, Deflater defl, int bufLen) Creates a new input stream with the specified compressor and buffer size. |
Class Methods
| Sr.No. | Method & Description |
|---|---|
| 1 | int available()
Returns 0 after EOF has been reached, otherwise always return 1. |
| 2 | void close()
Closes this input stream and its underlying input stream, discarding any pending uncompressed data. |
| 3 | int read()
Reads a single byte of compressed data from the input stream. |
| 4 | int read(byte[] b, int off, int len)
Reads compressed data into a byte array. |
| 5 | long skip(long n)
Skips over and discards data from the input stream. |
